    Upper Limits to the Magnetic Field in Central Stars of Planetary Nebulae
    More than about 20 central stars of planetary nebulae (CSPNs) have been observed spectropolarimetrically, yet no clear, unambiguous signal of the presence of a...

    Using autoencoders and deep transfer learning to determine the stellar parameters of 286 CARMENES M dwarfs
    Context. Deep learning (DL) techniques are a promising approach among the set of methods used in the ever-challenging determination of stellar parameters in M...

    Using color photometry to separate transiting exoplanets from false positives
    The radial velocity technique is currently used to classify transiting objects. While capable of identifying grazing binary eclipses, this technique cannot...

    Using Gaussian processes to model light curves in the presence of flickering: the eclipsing cataclysmic variable ASASSN-14ag
    The majority of cataclysmic variable (CV) stars contain a stochastic noise component in their light curves, commonly referred to as flickering. This can...

    Using MASS for AO simulations: a note on the comparison between MASS and Generalized SCIDAR techniques
    Recent studies on the comparison between the Multi Aperture Scintillation Sensor (MASS) and Generalized Scintillation Detection and Ranging (G-SCIDAR) profiler...

    Validation of up to seven TESS planet candidates through multi-colour transit photometry using MuSCAT2 data
    The TESS mission searches for transiting exoplanets by monitoring the brightness of hundreds of thousands of stars across the entire sky. M-type planet hosts...

    VaTEST III: Validation of eight potential super-earths from TESS data
    NASA's all-sky survey mission, the Transiting Exoplanet Survey Satellite (TESS), is specifically engineered to detect exoplanets that transit bright stars. Thus...

    Velocities from Cross-Correlation: A Guide for Self-Improvement
    The measurement of Doppler velocity shifts in spectra is a ubiquitous theme in astronomy, usually handled by computing the cross-correlation of the signals and...
